To all whom'it may concern:

a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented a certain new and useful Improvement in En ine Fuel, of which the following is a speci cation.

My invention relates particularly to fuels adapted to be used in burners or internal combustion engines generally.

The object of my invention is to provide an efficient fuel for such use, which contains a comparatively heavy hydrocarbon, but the constituents of which are such as to enable the fuels to be utilized if desired in the same manner as the light hydrocarbon fuels previously used for this purpose.

Another object of my invention is to provide motor fuels containing hydrocarbons from which the lower parafline hydrocarbons above propane, up to and including heptane, are substantially absent.

Again, another object of my invention is to provide motor fuels containing in addition, to the comparatively heavyhydrocarbon an ester but which is preferably a volatile ester. I

Further objects of my invention will appear from the detailed description thereof contained hereinafter. v

For example, in carryingout my'invention, I may provide a motor fuel comprised of the following 90 to 92 parts by volume of kerosene,

8 to 10 parts by volume of ethyl acetate.

The kerosene may be any light hydrocarbon distillate having a specific gravity heavier than B. These are usually hydrocarbons from which the lower members of the paraffine series of hydrocarbons above propane and up to and includingheptane are substantiallyabsent. The proportion of ethyl acetate may be varied to some extent,

but it is desirable to use substantially more than 2% of ethyl acetate based on the weight of the fuel mixture.

Instead of the ethyl acetate, I may use one of a number of other esters, such for exam- I ple as methylacetate, amyl acetate,-butyl acetate, or the corresponding esters of formic acid, butyric acid, propionic acid.

It will be found that motor fuels made in this manner, while containing a very large percentage of comparatively heavy hydrocarbons, can, nevertheless, be used with the greatest advantage in internal combustion engines in the same manner that light hydrocarbons have been hitherto used, and with equally'advantageous results.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit thereof.

I claim: 4

1. A fuel comprisng from 90% to 92% of a petroleum distillate heavier than 50 B.,

6. A fuel consisting of 90 to 92% of a petroleum distillate heavier than 50 B., and
